Specification of Letter Patent.

Application filed July 20, 1911.

Patent ad Nov. 14, 1911.

Serial No. 639,579.

To all whom it may concern: Be it known that I, WILLIAM P. SARGENT,

a citizen of the United States, and a resident 'the application of too much paste; to prevent umming of the paste ap lying means and their accessories; to provi e for delivering paste from a comparatively deep receptacle even when the latter is almost empty; to commercially and successfully feed heated gums or other ag lutinants from the bottom of a paste pot to eep the paste agitated, and to provide an improved paster adapted in whole or in part for many uses and pur-' poses, but especially adapted for pasting wrappers or sheets as they are delivered from the wrapper feeder of my application serially numbered 639,577 filed July 20th 1911.

The invention will be claimed at the end hereof, but will be first described in connection with the embodiment of it, which I believe to be the best and which is illustrated in the accompanying drawings, in which Figure 1, is a side view, partly in section, illustratin a paster embodying features of the invention. Fig. 2, is a view, with arts removed, looking toward the left ban of the machine as shown in Fig. 1. Fig. 3, is a transverse sectional view taken on the line 3-3 of Fig. 1. Fig. 4, is a sectional view taken through the various rolls which aste and also through the backing r0 1. Figs. 5, 6, and 7, are views illustrating means for heating or warming the paste, and 8, is a sectional view illustrating a modification. I

In the drawin s 1 and 2, are sets of belts spaced apart an suitably driven. The belts receive between them sheets or wrappers for example", from the suction foot 3, whic as well as the mechanism for actuating it are 11 of the paste applicat .on roll 11.

end i .1 Fig. 6 and connecte fully described in m application serially numbered 639,577 file Q'uly 20th 1911. The belts run over suitable gui rollers 4, and over pulleys 5 and 6, of wh oh the pulleys 6 are mounted in a swing ng frame 7 pivoted at 8. To one side of the belts is arranged a paste pot 9 pivoted at 10. This paste pot 9 18 provided near the lelts with revoluble paste application rolls 11, spaced between the belts and mounted upon a shaft 12 carried by boxes adjustably secured to the walls of the paste pot. The 1 ans 11 are provided with a series of circumferential flanges 11' spaced apart. The shaft 10 which consti tutes the pivot for the p aste pot as has been said, is rovided with c 'lindrical paste rolls 13, and is rotated as by means of a sprocket pot and by a frame 17. The rollers .13, 15

and 11, are geared together by pin and hole gearing 18, so that they are all positively driven. The backing r0 .1 19, is 'ournaled in the frame 7 and is provided wit projectin thin disks 20, spaced apart and arrange oppositethe grooves bet veen the pro'ectitilns y t is arrangement the backii roll is protected from paste. The swin ging frame may be moved against the force of its spring 21, by cams 22 on the shaft 10, which cams operate upon arms 23, projecting forward from the frame 7.

Heat may be applied to the aste in the pot 9. For this purpose the sha t 10 may be made hollow and connezted up with a hot water circulating'systeni 24 heated, for example, by means of an electric heater 25 supplied with current by su table connections as diagrammatically illustr ated at 26 in Fig. 5. However, if pre erred, tie electric heater 27 may be placed in the as :epot 9, as shown in (l u with suitable circult connections, or the electric heater 28 may be applied to the exterior of the paste pot 9, as shown in Fig. 7

30 is a positively driven cam and it operates on a spring, or otherwise properly controlled, follower 31 and the latter is connected to a rock shaft 31, having an arm 31 connected by an adjustable link 32 with an arm on a rock shaft 33.

An arm 34 on the rock shaft 33 is connected by means of a link 35 with the aste pot 9, thus the cam 30, or more accurate y, the high part thereof, serves to tip the paste pot up and bring the paste application roll 11 up to its working position. The connections for working the paste pot from the rock shaft 31 are the same on each side of the machine and the foregoing description of one set of said connections 1s suflicient.

In use when the swingin frame 6 is moved into position for bringing the belts 1 and 2 close together, as shown for example in Fig. 1, a wrapper, sheet or web, in the resent instance a wrapper a,'is fed upward between the belts. The backing roll is carried by the swinging frame so that the rims of its projecting disks 20 are brought into contact with the wrapper a, as illustrated in Fig. 4. At the proper time in respect to the travel of the wrapper a, the paste pot is tipped up and the paste application roll 11 brought into contact with the Wrapper a and permitted to remain in contact long enough to apply paste over the desired area of the wrapper. Thereupon the paste pot 9 returns to its original position and the wrapper is carried forward. The fact that the paste application rolls are spaced between the sets of-belts enables the wrapper or sheet to be fed forward without bringing the paste into contact with parts of the machine. As shown, the guide rolls 4 are reduced in diameter as at 29, which is a convenient way of causing them to clear the asted ortions of the wrappers or sheets. The various rollers in the paste pot keep the paste agitated and serve to transfer it, even from near the bottom of the pot to the paste application roll. The intermeshing flanges or ribs on the rolls 11 and 15 serve to feed the paste in proper limited quantity and the disks on the backing roll arranged in the manner described between the flanges on the paste application roll, properly support or ack up the sheet or wrapper and when the latter has passed or has not yet arrived, are

not gummed up with aste. Evidently the spaces between the ri s on the paste feed roll 15 are filled with paste by the paste roll 13 and then the ribs on the paste application roll running in these spaces between the ribs on the paste feed roll have their end portions roperly' covered with paste, and 811106 the ri s on the backing roll are disposed opposite the spaces between the ribs on the paste application roll, the ribs on the backing roll are not liable to be pasted; thus the pasting operation isproperly performed, while at the same time, the paste is agitated and fed u from the bottom of the pot even when the atter is comparatively empty.

The backing roll 19 may be replaced by an air blast 100, and in this case the ribs 11, may be omitted. The air blast or the disks 20 constitute means to which paste may not be applied and for holding the paper in con tact with the paste application roll.

What I claim is:

1. A paster comprising the combination of belts between which sheets or webs are fed, a swinging frame for positioning one of said belts in respect to the, other, spaced revoluble disks constituting a backing roll and carried by said frame, a pivotal paste pot, means for tipping the paste potfand positively driven intermeshing paste, paste feed and paste application rolls whereof the last two are provided with overlapping flanges, the disks on the backing roll being spaced opposite the spaces between the flanges on the paste application rolls, substantially as described.

2. In a paster the combination of a paste pot, a revoluble cylindrical paste roll mounted in the pot, a revoluble paste feed roll having perip eral flanges running on the c lindrical surface of the paste roll, a revo uble paste application roll having peripheral flanges running in the spaces between the flanges on the paste feed roll, and a backing roll having dlsk-like flanges opposite the spaces between the flanges on the paste application roll.

3. In a paster the combination of a paste I pot, a paste application roll adjustably mounted at the outlet of the pot and having peripheral flanges, a paste feed roll mounted in the pot and having peripheral flanges arranged to run in the spaces between the flanges of the paste application roll, a cylindrical paste roll mounted in the pot and having its surface arranged for cooperation with the flanges onthe pastefeed roll, and 1 means for revolving said rolls, Substantially as described.

4. In a paster the combination of circumferentially ribbed paste application and backing rolls, the ribs of one being arranged opposite the spaces between the ribs of the other and there being space between the ends of the ribs for the passage of a sheet or web.

5. Ina paster the combination of a paste pot, a train of rolls arranged in the pot and aving pin and hole gearing. and whereof one 0 said rolls is ribless and two of said rolls are provided with overlapping circumferential ribs, and means for driving said rolls, substantially as described.

6. In a paster the combination of a swinging frame provided with a backing roll, a paste pot, revoluble paste rolls in the pot,

and a revoluble shaft for driving one of said for holding a sheet or we) in contact with rolls and provided with cams for operating the paste application roll substantially as the swinging frame, substantially as described.

7. In a paster the combination of a paste application roll, backing means spaced clear 0 the paste application roll, and provisions described.
